Now, after an all-too-brief period of peace, a new mission is unveiled. Kidnapped, caged, and whisked away to a foreign land by animal smugglers, the Angry Birds escape the clutches of their bungling captors–but they soon discover a deeper purpose. Slews of rare and endangered birds are being held captive in Rio de Janeiro, and it’s up to the Angry Birds to rescue their winged friends by cracking open their cages and setting them free.
